Background and Aim : In Guinea, the supply of electrical energy still remains a major challenge, especially in rural areas. However, Guinea's hydroelectric energy potential is enormous, more than 6000 MW, with a very dense hydrographic network of 1165 rivers, which finds its origin mainly in the Fouta-Djallon. To date, only 5% of this potential has been developed and only benefits nearly 10% of the Guinean population. This study is part of this aspect, for the improvement of electricity supply in isolated areas of the country. Its objective is to evaluate the hydroenergetic potential of the waterfall in the Gueeni village on the Kokoulo river in Pita. Method : This study is based on field measurements, the use of physical formulas and sizing software to determine the energy characteristics of the site. Results: The main results obtained are: equipment flow (9.781m3/s), gross head (31 m), net head (28.264 mm), hydraulic power (3000 kW) and power net of falling water (2700 kW). Conclusion: The results obtained represent important basic data for the construction of the small power plant on the Gueeni site. Keywords: Hydroenergy potential, waterfall, Gueeni village, Electric power

The hydraulic turbine is considered as a heart of the hydropower plant because of its important function in the whole process of electrical energy production. Turbine´s efficiency calculation is analytically demanding and dependent on parameters that are often obtained only by a theoretical estimation. Therefore, using its accurate model, which takes into account its efficiency, is necessary to achieve realistic and relevant results. The article briefly surveys current knowledge and methods of designing the hydraulic turbine model. The new idea consists in that a fuzzy system was used to create turbine´s efficiency model based on a measured operating data of the turbine flow rate and its mechanical speed without any need of knowing exactly the turbine parameters. Such a model can be used in the design and development process of an optimal energy control of a hydraulic turbine, as well as in the effective process of determination the actual turbine’s wear rate. The achieved results were obtained using the computational tools of the Fuzzy Toolbox in the MATLAB.

Adding a new micro hydropower component to an established barrage, such as the Serayu Barrage in Central Java Province, poses significant structure risks and potentially compromises the stability of the structures. To mitigate these negative impacts, physical modeling was conducted at our hydraulic laboratory to accurately replicate 600 meters of the Serayu River, including the 110-meter-wide Serayu Barrage structure at a scale of 1:40. Multiple scenarios were examined to simulate hydrodynamic conditions and sediment transport along the barrage structure. Notably, downstream scouring conditions were identified as a crucial parameter affecting the structure’s stability. Results obtained using a design discharge of 2,470 m3/s revealed concerning findings, with an observed 4 to 6 meters deep scouring downstream near the end sill of the weir. Immediate mitigation measures using riprap are imperative to prevent further damage to the weir structure. This paper investigates several configurations for riprap protection to address the scouring problems. After implementing a full riprap arrangement downstream of the end sill, the scouring depth was reduced significantly and pushed far downstream. Looking at it from an economic standpoint, placing a full riprap configuration for downstream protection is a more financially efficient option over an extended period.
